In one embodiment, as shown in fig. 2, a method for fast charging and cooling a new energy vehicle is provided, which is described by taking the method as an example of being applied to the terminal in fig. 1, and includes the following steps:
201. when a starting signal of quick charging is received, through the vehicle control unit, cooling liquid in the water pump is controlled to respectively flow in from a water inlet of the all-in-one controller and a liquid cooling water jacket inlet of a quick charging harness and respectively flow out from a water outlet of the all-in-one controller and a liquid cooling water jacket outlet of the quick charging harness, wherein the quick charging harness refers to a charging wire of a new energy automobile end, the quick charging harness is connected with the all-in-one controller in series, and the all-in-one controller is used for high-voltage power distribution;

204. when an opening signal of the warm air system is received, the cooling liquids flowing out of the water outlet of the multi-in-one controller, the liquid cooling water jacket outlet of the quick charging wire harness and the battery cooling liquid circulating system respectively are controlled to converge to serve as a total cooling liquid, and the total cooling liquid is controlled to enter the warm air system to heat a cab of the new energy automobile.
In step 201, the start signal of the quick charging refers to a charging start signal generated by the vehicle control unit when the charging pile starts to charge the new energy vehicle after the quick charging harness of the new energy vehicle is connected with the charging pile.
The type of the cooling liquid is not particularly limited in the embodiments of the present invention, and includes but is not limited to: liquid water. Specifically, the vehicle control unit sends a control signal to control the cooling liquid in the water pump to flow in from a water inlet of the all-in-one controller and a liquid cooling water jacket inlet of the quick charging harness and flow out from a water outlet of the all-in-one controller and a liquid cooling water jacket outlet of the quick charging harness respectively. When the all-in-one controller is used for power distribution, the temperature of devices in the all-in-one controller can be increased, so that the cooling liquid flowing from the water inlet of the all-in-one controller can also dissipate heat of the all-in-one controller.
When the whole vehicle starts to be charged, the temperature detection module collects the temperature of the quick charging harness in real time and transmits the collected temperature to the whole vehicle controller, and the whole vehicle controller realizes the control of the outflow of the cooling liquid in the water pump according to the obtained temperature of the quick charging harness at each moment.
In step 204, the start signal of the heater system refers to a signal when the user starts the heater system of the new energy automobile. When the vehicle control unit receives the warm air system, whether the total cooling liquid needs to be heated is judged according to the temperature of the total cooling liquid, then the total cooling liquid is controlled to enter the warm air system, and the total cooling liquid passing through the warm air system flows back to the water pump.
According to the method provided by the embodiment of the invention, the cooling liquid is used for dissipating the heat of the quick charging wire harness during charging, so that the temperature of the quick charging wire harness during charging can be reduced, and the charging efficiency of the quick charging wire harness is improved; meanwhile, the heat dissipation capacity of the charging harness is improved in a liquid cooling mode, the size of the charging harness is effectively reduced, and the charging harness is beneficial to straightening.
In combination with the above embodiments, in one embodiment, as shown in fig. 3, each fast charging wire in the fast charging harness is composed of a high-voltage wire, a heat conductive material, a liquid cooling water jacket, a filling material, and an outer layer wrapping wire from inside to outside.
The filling material is used for protecting the liquid cooling water jacket so as to prevent the liquid cooling water jacket from being directly exposed when the outer layer wrapping line is broken.
Specifically, in the charging process of the new energy automobile, the coolant in the liquid cooling water jacket is constantly in flow change, so that the temperature of the charging harness is maintained in a stable temperature range; the charging speed of the new energy automobile cannot be reduced due to the fact that the temperature of the charging wire bundle is too high.
According to the method provided by the embodiment of the invention, the cooling liquid in the water jacket is cooled, so that the charging harness can be maintained in a stable temperature range in the charging process, and the charging efficiency of the new energy automobile is improved.

Wherein the preset temperature refers to a preset temperature range. Specifically, if the temperature of the cooling liquid is within the preset temperature range at each moment, the cooling liquid outflow amount of the water pump does not need to be adjusted, and the original cooling liquid outflow amount is still kept flowing into the liquid cooling water jacket inlet of the quick-charging harness. If the temperature of the cooling liquid is not within the preset temperature range at any moment, the flow rate of the cooling liquid of the water pump needs to be adjusted through the vehicle control unit, and as for the adjustment amount of the flow rate of the cooling liquid, the adjustment amount needs to be determined according to the first temperature difference.
According to the method provided by the embodiment of the invention, the coolant outflow of the water pump at each moment is adjusted through the preset temperature and the temperature of the coolant at each moment, and the coolant flows into the inlet of the liquid cooling water jacket of the fast charging harness, so that the fast charging harness can be stably maintained, and the charging speed of the new energy automobile is increased.
With reference to the content of the foregoing embodiment, in an embodiment, the preset temperature includes a first preset temperature and a second preset temperature, and the first preset temperature is less than the second preset temperature; determining a first temperature difference value according to a preset temperature and the temperature of the cooling liquid at each moment, comprising:

and if the temperature of the cooling liquid at any moment is greater than the second preset temperature, taking the difference value between the temperature of the cooling liquid at the corresponding moment and the second preset temperature as a first temperature difference value.
The first preset temperature refers to the minimum value in a preset temperature range, and the second preset temperature refers to the maximum value in the preset temperature range. The magnitude of the first temperature difference corresponding to different time instants may be different.
Specifically, if the temperature of the cooling liquid at any moment is lower than a first preset temperature, the vehicle control unit increases the flow rate of the cooling liquid of the water pump at the corresponding moment according to the difference between the temperature of the cooling liquid at the corresponding moment and the first preset temperature. And if the temperature of the cooling liquid at any moment is higher than the second preset temperature, the vehicle control unit reduces the flow rate of the cooling liquid of the water pump at the corresponding moment according to the difference between the temperature of the cooling liquid at the corresponding moment and the second preset temperature.
According to the method provided by the embodiment of the invention, the first temperature difference value can be determined through the preset temperature and the temperature of the cooling liquid at each moment, so that the control of the whole vehicle controller on the outflow of the cooling liquid of the water pump is realized.
In combination with the above embodiments, in one embodiment, the method for controlling the coolant of the water pump to flow into the liquid cooling water jacket inlet of the fast charging harness according to the coolant outflow includes:

and controlling the cooling liquid of the water pump to flow into the liquid cooling water jacket inlet of the quick-charging wire harness according to the cooling liquid outflow adjusting signal.
Specifically, the vehicle control unit calculates the coolant outflow of the water pump according to the first temperature difference, and then the vehicle control unit sends a coolant outflow adjusting signal to the controller of the water pump according to the coolant outflow, so as to control the coolant outflow of the water pump.
According to the method provided by the embodiment of the invention, the coolant of the water pump can be controlled to flow into the liquid cooling water jacket inlet of the fast charging harness through the coolant outflow rate, so that the temperature of the fast charging harness is adjusted to be maintained within a preset temperature range, and further, the new energy automobile can keep a stable charging speed.
